Hello everyone ! I have a Jotul F100 bought in Europe about 4 years ago. I never had any problem with it ,until now. It seems like the air vent handle is set on high air and if I move it to the left nothing happens and the fire is still burning very fast. I tried to open the stove ,but I can't get to the air vent system because I can't remove the top. I think something inside the system moved from its place. I don't know when the problem started exactly ,because I was away for a while and my grandma used the stove. I attached a photo with the air vent system. Maybe some of you had the same problem or got the top of the stove open. Thank you !
